Goodman 1370906S Furnace Limit Switch

The 1370906S is a genuine OEM high-limit switch for Goodman GUPX050-3B gas furnaces. Mounted on the heat exchanger or blower deck, this thermal safety control opens the gas/ignition circuit if supply air temperature climbs too high — protecting the furnace and your home from overheating caused by restricted airflow, a dirty filter, or a failed blower.

Specifications

Trip temperature: 150°F (opens on rise)
Insert length: 7 inches
Type: Automatic-reset high-limit safety switch
Fit: Goodman GUPX050-3B furnaces
OEM part number: 1370906S

OEM vs. Generic

This factory Goodman limit is set to the exact 150°F trip point and 7" probe length your furnace was engineered around. Generic limits with a different setpoint or probe depth can trip early (short-cycling and no heat) or trip late (defeating the overheat protection). For a life-safety control, the OEM part guarantees correct calibration and fit.

Installation Difficulty: Easy

A quick two-screw, two-wire replacement. Shut off power at the breaker, note or photograph the wiring, remove the two mounting screws, slide the old switch out, and insert the new one to the same depth. Reconnect the spade terminals and refasten. Estimated time: 15–20 minutes. After installation, run a heat cycle and confirm the furnace holds without tripping.
